IGO SUSTAINABILITY REPORT 2020

TRANSPARENCY Information on IGO’s operational, financial and sustainability performance is issued in a timely manner through several communication channels, including media releases, ASX announcements, voluntary ESG assessments, social media and community meetings. We provide responses to stakeholder enquiries and remain an active participant in industry associations. During FY20, tax transparency, human rights, tailings management and our climate change management approach have been of specific interest to our stakeholders. Tax transparency At IGO, we are committed to open and transparent dealings with all our stakeholders. Payment of tax is an important element of our contribution to the economic development of Australia. During the year we released our Tax Transparency Report for FY19, including details on our approach to tax strategy and governance, effective tax rates and tax contribution summaries. The report was prepared in conformance with the recommendations of the Board of Taxation’s Voluntary Tax Transparency Code. Our FY20 Tax Transparency Report will be released in November 2020 and made available on our website. Read more about our tax contributions and our support of regional economic development in the Optimising Business Value section of this report, page 85. Human rights Governments, investors and civil society expect businesses to meet their responsibilities under the United Nations Guiding Principles on Business and Human Rights (UNGPs). IGO take its responsibilities seriously and support the general proposition that large businesses have a key role in combating modern slavery. We agree that no business should tolerate modern slavery or other serious abuses of human rights in their operations or across their supply chains. IGO is committed to upholding the fundamental human rights of all people we engage with in our business. We aspire to be a business which recognises and respects the rights and dignity of all people by putting in place policies and procedures which aim to stamp out unethical practices from within our global supply chains and by ensuring all our people are free to operate in an inclusive environment regardless of race, religion, marital status, political beliefs or experience. Our approach to human rights is aligned with the UNGPs. We explicitly state our respect for human rights in our Code of Conduct, and our purpose and values reflect this. Our Human Rights Policy clearly articulates our goals to undertake the following: • champion and promote a workplace culture which encourages diversity and inclusion without regard to factors such as sex, marital status, race, impairment, religion, political beliefs or social preference; • recognise and respect Aboriginal cultural heritage and work with Aboriginal communities affected by our operations in an open, transparent, and collaborative manner to ensure we continue to deliver positive outcomes for all members of these communities; • not tolerate any form of forced labour or servitude including child labour and human trafficking; • comply with our obligations under the Australian Modern Slavery Act 2018 by undertaking risk assessments to identify those parts of our business and supply chains where there is a risk of modern slavery practices taking place and work with our suppliers to improve their standards; • prohibit all forms of corruption and bribery as well as all forms of retaliation, discrimination, harassment and intimidation against any person reporting a breach of this policy; and • focus on continued learning and development for all employees to ensure our business practices are consistent with our values to promote and uphold the rights and dignity of all people. We are actively aware of our obligations under the Australian Modern Slavery Act 2018 that establishes the requirement for publicly disclosed modern slavery reporting on actions to address modern slavery risks. In FY20, we engaged industry experts to undertake a preliminary risk assessment, gap analysis and due diligence action plan to assist in the development of our first Modern Slavery Statement. Modern slavery risks associated with IGO’s operations and supply chains were identified, guided by global best practices including the UNGPs, the UN Global Compact Ten Principles and the OECD Due Diligence Guidance for Responsible Business Conduct. Gap analysis outcomes and best-practice recommendations were highlighted, with key findings to be communicated in the FY21 Sustainability Report. COVID-19 resulted in delays to our modern slavery risk assessment work and the release of our first Modern Slavery Statement. This statement will be made publicly available on our website in early 2021. Tailings dam management disclosure Tailings storage facilities are reservoirs or dams that store mine tailings. Mine tailings are the fine- grained waste rock material, suspended in a water slurry, that are discharged from an ore processing plant following the extraction of the desired metal or mineral. Inappropriate storage or mismanagement of tailings facilities has the potential to cause catastrophic safety, health and/or environmental risks. Given this, IGO supports the need for the public disclosure of tailings storage management practices. Information relating to IGO’s tailings storage facilities is published on our website. Further information regarding our tailing storage management can be read on page 56 of this report. Taskforce on climate- related financial disclosures IGO recognises the importance of providing timely and business- specific information on our approach to managing climate-related risks and opportunities to stakeholders and investors. In FY20, we completed a workplan to align with the recommendations of the Taskforce on Climate-related Financial Disclosures (TCFD). This included a detailed assessment of climate-related risks and opportunities over relevant time- horizons, scenario analysis to test the resilience of our existing business strategies and the introduction of an internal carbon price to inform financial planning. The full disclosure can be found in on page 65 of this report. Nova Operation Tailings Storage Facility 38 — IGO SUSTAINABILITY REPORT 2020 BUSINESS INTEGRITY IGO SUSTAINABILITY REPORT 2020— 39
